IBOILED-POTATOSLICING MACHINE.

Application filed. December 15, 1921.

. Machines, of which the following is a specification.

The object of this invention is to provide a new and improved machinewith which boiled potatoes may be' sliced, for the purpose of makingpotato salads.

This and other objects of this invention will be fully illustrated inthe drawing, described in the specification and pointed out in theclaims at the end thereof.

In the accompanying drawing:

Figure 1 is a topplan view of the potato slicing machine.

Figure 2 is a perspective view of the potato slicing machine.

, In the several figures of the drawing like reference numerals indicatelikeparts.

For the purpose of making potatosalads the potatoes are first boiled,peeled, and allowed to cool off. The coldboiled potatoes are then slicedinto suitable slices and mixed with a dressing and possibly otheringredients to complete the salad. Heretofore the slicing of thepotatoes has been done by hand with the result that the slices were madeirregular in size. Hand slicing. is also slow and expensive.

The machine forming the subject matter of this invention operatestoflcut the slices evenly at a rapid rate of speed never before attainedby the hand method. It comprises the base or bed plate 1 onwhich themagazine 2is mounted. This magazine is made up of the two sides 3 amid,the open front end 5 and rear end formed by themovable pusher plate 6.In the sides. are formed the runways 7 and 8. The pusher plate 6 isprovidedwith a pair of guide bars 9 and 10 which project rearwardly andengage into the runways 7 and 8 forv the purpose of guiding the pusherplate in a straight line horizontal movement between the sides 3 and 4from one endto the other end thereof.

The pusher plate is movedback andrforth by the connecting rod which isconnected to the usher plate with one end thereof for whic purposegthepusher plate isprovided with a pair of lugs-12 and 13 n order toSpecification of Letters Patent.

form suitable bearings for the wrist pin 14 carried on the end of theconnecting rod 11.

The other end of the connecting rod connects to the crank pin 15 formingpart of the crank disc 16'. The crank disc is keyed to the left handendof theshaft 17 which is mounted to rotate in the bearings 18 providedon the top of the standard 19.

Keyed to the right handend of the shaft 17 islthe bevel gear 20 whichmeshes with the bevel pinion 21 keyed to the power shaft 22. The powershaft 22 is mounted in the bearings 23 and 24 and has the hand wheelkeyed to one end thereof by means of which the machine is driven. Alsokeyed to the shaft 22 is the spur gear 26 which mesheswith the pinion 27keyed to one end of the shaft 28. The other end of the shaft 28'has thecutting wheel 29 keyed thereto by means of which the potatoes are slicedas will hereinafter be described.

Mounted in the standard 19 and projecting out from under the crank disc16 is the stud 30. A lever 31 divided into the long arm 32 and the shortarm 34is mounted to rock on this stud. The short arm carries on itsouter end the anti-friction roller 10 which is adapted to make contactwith the periphery of the cam tO forming part of the crank disc 16.

The long arm 32 projects forward to one side of the magazine and has thelinks t1 and 42 connected thereto. These links connect the arm with theleaves 44: and 45 which are hinged to the top of the magazine, one atthe front and the other at the rear thereof.

The cam 40 has two cam surfaces formed thereon, one which operates torock the short arm 34L away from the center of rotation thereof, and theother which allows the arm 34to move back toward the center of rotationof the cam. This latter motion is effected by the spring 46 which isstretched between the arm 32 and a suitable point on the bed plate ofthe machine. WVhen the short arm of the lever is forced outwardly thelong arm is raised and in so doing rocks the leaves 44 and; 45 so as toopen the top of the magazine. The magazine can then be filled withpotatoes. For this purpose the top of the magazine is kept open during.the rearward stroke of the pusher plate the cam 10 operating to do thisduring one half of its revolution.

On the forward stroke of the pusher plate the cam permits the spring topull the arm 32 back and in so doing makes the leaves 44 and 45 folddown over the top of the magazine to keep the potatoes in place therein.In this way the potatoes can only be forced through the open end wherethey are being cut into slices by the wire mesh mounted at the open end5 and the cutting wires of the cutting wheel rotating on the outside ofthe open end.

The cutting wheel 29 with which the potatoes are sliced as fast as theyare pushed through the open end of the magazine, comprises a series ofradial arms 35 which branch out from their common hub 36. At the outerend these arms are curved in the direction in which the wheel is rotatedbesides being set to project angularlyto the rear toward the free end ofthe magazine. A cutting wire is stretched between the curved end of eachof the arms and a suitable point on the hub to form a series of radialcutting wires 37 which are moved past the open end of the magazine onthe rotation of the cutting wheel.

The end 5 of the magazine 1 is not entirely open but has a coarse wirenetting 38 placed across it. This netting does not obstruct the potatoesas they are forced through the end 5 ready to be sliced by the cuttingwires 37 but operates to cut the potatoes into horizontal sections asthey are being forced therethrough. In this way the potatoes are notonly cut in vertical slices of even thickness but are also cut intosections lengthwise of equal dimensions. A uniform product is thusproduced by the machine which not only improves the appearance of thesalad made with potatoes cut with this machine, but also improves thetaste thereof because each slice being of the same thickness anddimension absorbs the same amount of the ingredients with which thepotatoes are mixed to make up the salad.

The operation of the potato slicing machine is as follows: 7

The potatoes after being boiled are. al lowed to cool OK so that theycan be handled for the purpose of peeling them. The op erator then fillsthe magazine 1 with these potatoes and starts to rotate the handwheel25. This operates to move the pusher plate into the magazine while thecover is placed over it to prevent'the potatoes from being forced outthrough the top of the magazine. The cover is held down over themagazine during'the forward movement of the pusher "plate caused'by'thefurther rotation of the hand wheel. At the same time the pusher plate isbeing moved forward to force the potatoes through the wire mesh at theopen end of the magazine, the cutting wheel is being rotated, and aseach of the cutting wires swings past the front of the magazine, thepotatoes forced out of the open end of the magazine are being sliced offthereby.

This takes place until the pusher plate reaches the end of its forwardtravel and all the potatoes have been forced out of the magazinethereby. On further rotation of the hand wheel by the operator thepusher plate begins to move rearwardly while the cover swings open so asto allow the operator to again fill the magazinewith potatoes that willbe forced therethrough and cutby the cutting mechanism on the returnmovement of the pusher plate as heretofore pointed out. This cyclecofoperation repeats itself over and over again as long as the hand wheelisbeing rotated and the magazine is being filled with potatoes.
